Corrosion Glossary


 

 

wash primer

A thin, inhibiting paint, usually chromate pigmented with a polyvinyl butyrate binder.

weld cracking

Cracking that occurs in the weld metal. See also cold cracking, hot cracking, lamellar tearing, and stress-relief cracking.

weld decay

Intergranular corrosion, usually of stainless steels or certain nickel-base alloys, that occurs as the result of sensitization in the heat-affected zone during the welding operation.

wetting

A condition in which the interfacial tension between a liquid and a solid is such that the contact angle is 0º to 90º.

 

 

wetting agent

A substance that reduces the surface tension of a liquid, thereby causing it to spread more readily on a solid surface.

white liquor

Cooking liquor from the kraft pulping process produced by recausticizing green liquor with lime.

white rust

Zinc oxide: the powdery product of corrosion of zinc or zinc-coated surfaces.

work hardening

Same as strain hardening.

working electrode

The test or specimen electrode in an electrochemical cell.
